| 16F88: output_high(pin_a5) stays low - output_a(0x20) works |

hi,
on 16F88 i need pin_a5 to work just like the others.
if i set a5 and a6 to high, only a6 goes high. if only set a5 to high it works just fine. a5 stays low (only) in combination with a6 and a7. what am i doing wrong?
thanx for helping
| Code: | #include <16F88.h>
#use delay(clock=4000000)
#fuses NOWDT,INTRC_IO, NOPUT, NOMCLR, NOLVP, NOBROWNOUT, NOCPD, NOWRT, NODEBUG, NOPROTECT, NOFCMEN, NOIESO
void main()
{
setup_adc(ADC_OFF);
set_tris_a(0);
while(1)
{
Output_high(PIN_A5);
Output_high(PIN_A6);
delay_cycles(100);
Output_low(PIN_A5);
Output_low(PIN_A6);
delay_cycles(100);
}
}

| I'm looking at the datasheet. RA5 is designated as an INPUT only. Unfortunately, you'll have to find another pin; if you're out of pins, then swap RA5 with another pin that you are using as an input. |

Read the datasheet. In page 10 you will see that A5 is an INPUT PIN
Best wishes,
